4 Claims.

Thepresent invention relates to bus or car window construction, and more particularly to improved means for holding the stops of a window sash casing in place on the post piece of the `gwindow frame, such stops being either inside or outside type, an object of the invention being to provide a construction which will reliably hold the stopsin their proper positions in the frame, and will permit them to be easily and quickly Vfastened and unfastened.

With the above and other objects in View, embodirnentsV of the invention are shown in the accompanying drawing, and these embodiments will behereinafter more fully described with rei- 15,V erence thereto, and the invention will be finally pointed out in the claims.

As'the construction', according to the'inven,n tion, is the same on each side of, the window opening, only one side or post of said opening 201Wi1l be shown in the illustrated adaptation of the invention.

' Fig. 7 lis a vertical sectional view, taken along the line 7 7 of Fig. 6.

Similar numerals of reference will be used to denote like parts inthe several figures of the drawing.

Referring to Figs. 1 to 5 of the drawing, 1 represents the window casing, and 2 generally denotes the outside stop which is made of metal. This outside stop comprises a comparatively wide member 3 which has a leg 4 abutting the post, a member 5 that extends inwardly and is spaced from the post and is then stepped iiush with the leg 4 and abuts thepost, as shown at 6, 'and immediately'beyond the riser 7 of the stepped portion is acomparatively narrow member 8 which is integral with the stop v2'and parallel to the -member .3,.the spacing between the riser 7 and (Cl.A 189-73) member 8 forming a groove 9. The portion 6 exn tends beyond the member 8 and terminates in a lip lo that is parallel to said member.

The stop is secured to the post, at suitable intervals by screws l1, (only one of which is shown) the space between the member 5 and the post preferably containing any suitable packing i2, such as felt, so as to prevent Vdirt or moisture from entering.

The window sash glass 13 has its side edges 65.y bound in glazing tape 1i and contained in a channel side strap 15 adapted to slide within felt channels 16, these channels 16 being backed by a metal retaining strip which has a portion 17 that extends behind the channel, and an outer portion 1.8 that extends along the outer face of the channel and abuts snugly against the inner surface of the member 3, said portion 18 terminating in a lip 19 that overlaps the outer leg of the channel and serves to keep the latter in place. Springs 20 secured by the screws 11 to the member 5 yieldingly back up the metal strip and channel.

Tl'ie inside stop 21 is of generally H-shape, and is inserted by rolling one leg over the slightly 8G, protruded end 22 of the member 8 into the chan nel 9 and in abutting .relation to the inner lig of the felt channel 16, the outer leg seating upon the member 6 adjacent the lip lo. Alip 23 onV the stop overlaps the end of the inner leg of the V felt channel 16 and co-operates with the lip 19 in holding the channel in place.

When the inside stop is thus placed in position, it will be noted that the pressure of the felt channel is outwardly upon the outer end of the stop 21, pressing the inner end of the inner leg against the inner wall l of the groove 9 about the protrusion 22 on the end of the member 8 as a fulcrum, the stop being thus held in position and in turn retaining the felt channel 16.

.In order to fasten the inside stop in position the inner leg of the stop is provided at suitable intervals along its edge disposed in the groove 9 with notches 24 having inclined slots 25 extend ing therefrom in a generally longitudinal direc- 10D tion and which are adapted to be engaged by projecting pins 26 secured to the member 8, the e gagement being eiTected by rst engaging the pins in the notches 24 and thereupon moving the stop longitudinally, whereupon the pins enter the slots with a wedging action to secure the stop in place. The stops are thereupon locked in position, and for this purpose the member 8 is provided with a transversely bent lug 2'7 disposed in the plane of a screw 28 provided in an enlargement 29 of the Il Q cross part of the stop. With this screw withdrawn a sufficient distance to clear the lug 27 the stop may be freely moved in a longitudinal direction either' to engage or disengage it. When fully engaged the screw 28 is screwed in as shown in Figs. 3, 4 and 5 into obstructing position behind one end of the lugV 2.7 thus preventing retractive movement onthestop. ,v l

In Figs. 6 and '7 I have shown a modification in which the outside stop is removable, and is adapted to be positioned and locked in a substantially` similar manner to the first embodiment. In this case the outside stop has a comparatively-narrow member 30 having an inwardly directed protruson 3l at its end, while the member 5 is spaced from the post as described, but is also spacedv from the member 30 so as to form a groove 32, the inside stop 21 being integral with the-parts of the outside stop just described, and the felt channel retainer 16-17 being reversed as compared with the retainer of the rst embodiment,

the lip 19 overlapping the inner leg of the channel..

In this modified construction the same method of positioning the sash is employed, since in this instance, the sash is put in position from the outside of the vehicle instead of the inside, it being merely necessary to pull the outer leg of the felt channel 16 outwardly, locate the sash therein, and then roll a separate comparatively widey outside stop member 33 over the member 30 and force it into the groove 32, this member 33 having a lip 34 which overlaps the adjacent leg of the channel and co-operates with the lip 19 to hold the felt channel in place. When the member 33 is in position it is firmly held by the groove 32, the outward thrust of the outer leg of the felt channel `and the member y30.

In order to fasten the stop inposition it is-provided, in a substantially similar manner to. the nrst embodiment, along its edge disposed in the groovek 32 with notches 34, having inclined slots 35 extending therefrom and which are engaged by pins 36 secured to the member 32. For the purpose of locking the stop in position a stop block 37 is slidably mounted in a'transve'rse slot 38 formed in the base of the groove 32 and extending inwardly in the member 5, a 'screw 39 rotatable in` an aperture in the member 32 being threadedl into the block and adapted uponl being turned to impart transverse movement to it. Within the member 33 there is provided a rectangular notch li() adapted toreceive the block in the locking position and a Vlongitudinal notch 41 extending from one side ofthe notch- 34 and which clears the screw in the .unlocked position and during longitudinal movement of the stop 33. It will be obvious that in the unlocked position the screw 39 isv turned to'move the block 37 inwardlyout of blocking relation from the notch 40, and in the locked relation the screw is turnedin the opposite direction drawing the block tightly against the inner surface of the member 30 vand in blocking relation in thenotch 40.

I have illustratedand described a preferred and satisfactory embodiment of the invention but it will be obvious that changes may be made there-1 in, within the spirit andscope thereof, as dened in the appended claims. Y

Having thus described my invention, what I- claim and desire to secure by Letters'Paten't is:--

1. In a window construction, a window post, a glass sash having its edge in relation to said post, astop xed to said post and vdisposed at one side of said sash to retain it, a removable stop member disposed at'the other side of said sash and abuttingly engaged at one edge against said xed stop in the assembled relation, said removable stop member adapted to be moved longitudinally of said post, inclined bayonet slot and pin means cooperating between said post and said removable stop member adapted to interlockingly engage with a wedging action uponV movement ofsaid .removablestop member in one direction and to disengage upon movement in the other direction, the edge of said removable stop member being out of frictional contact with said xed stop during said longitudinal movement.

2. In a window construction, a window post, a glass sash having its edge in relation to said post, a stop fixed to-'said post and disposed at one side of said sash to retain it, a removable stop member disposed at the other side of said sash and abuttingly engaged against said fixed stop in the assembled relation, said removable stop member adapted to be moved longitudinally of said post, said removable stop member having inclined bayonet slots in its edge, and pins fixed to said post adapted to interlockingly engage said slots with a wedging action upon movement of said removable stop member in one direction and to disengage upon movement in the other direction, the edge of said removable stop member being out of frictionalv contact with said fixed stop during said longitudinal movement.
